You can’t fail to have noticed the recent storm over farming and the environment. So what is this all about and what is the truth of it? Well, essentially the main thrust of the argument is farming = bad, everyone should go vegan. In a bit more detail, the claim is that meat production emits large amounts of greenhouse gasses (GHGs) and therefore is causing global warming, with some claims putting farm emissions levels on a par with the transport industry.
This leads to the conclusion that we should “eat less meat”. What we’re hoping to do with this post is to dispel this conclusion as misguided, set out the actual evidence and show how you can make a choice that actually benefits the environment.
Returning to that claim, even just intuitively this doesn’t feel right does it? I mean, compare the great British countryside (green fields, woodland, animals grazing) with cities and road networks (air thick with smog and pollutants). However, this claim had an origin; the NOA Long Shadow report in 2006 was the initial place where these figures appeared, stating that transport, industry and farming all had a global GHG contribution of around 17%. What the vegan propaganda fails to tell us is that the authors of this report fully retracted this conclusion when it was pointed out to them that they had assessed the different sectors on entirely different bases, skewing the results to make meat production appear far worse than it is. If you re-calculate the figures on a more consistent basis then meat production world wide is actually well below 10% of emissions.
What these “meat is bad” arguments fail to explain is that by maintaining the British countryside as a mixture of permanent pasture, moorland and woodland, on which sheep and cows grow extremely well, we are providing a huge carbon sink. This natural green space sequesters CO2 from the atmosphere, combatting global warming. In fact, we have done the calculations for our farm and can show that we are net carbon negative. Our farm’s annual sequestration is approximately 30 tonnes CO2 greater than what we emit, which would be roughly equivalent to running 20 cars for the year! We are environmentally conscious but we’re not doing anything ground-breaking - this is typical of traditional UK livestock farming methods.
So, how does the “meat is bad” argument get around this fact then? Well because not all global agriculture is like this. The data trotted out by vegan enthusiasts and more recently by that very poor “documentary” the BBC produced is extracted solely from intensive feed-lot type farms. The BBC programme featured these type of farms in South America and South Africa and (despite the BBC claiming to be impartial) didn’t present anything of traditional British farming methods.
The Truth is that if you keep animals in these feed-lot systems then yes they produce GHGs, they require a lot of water, they require large quantities of imported feed (maize, soya etc) and there is essentially no sequestration of CO2 because there isn’t a blade of grass in sight. So yes, this system of farming is not particularly sustainable or environmentally friendly BUT it absolutely does not stand that the environmental impact of a farm like this can be blanket applied across the entire industry, especially here in the UK.
The alternative to eating meat is purported to be the entire world turning to a “plant based diet” because this is seen to be better than the selectively picked emissions data of meat production. If we examine this a little further, we see it falling down in a number of areas. Firstly, approximately 65% of the UK is unsuitable for growing crops. This means we would have to import huge amounts of plant based product, with the corresponding increase in air miles on all our food, generating large amounts of GHGs. Sure, imported meat has the same issue but it is not necessary to import meat from the other side of the world – buy locally produced food from a sustainable farm.
Secondly, don’t let the ethics argument fool you. Anyone who claims to only eat a plant based diet because they don’t like killing animals is a hypocrite. In order to grow crops on an industrial scale, it requires huge amounts of chemical sprays – pesticides, herbicides & fungicides. So not only does this kill off a huge number of animals (albeit mostly insects not ones with cute faces) it creates huge areas of monoculture completely lacking in any form of bio-diversity. Let’s not forget that insects form the basis of food chains for a massive swathe of the world’s eco-system. For example, bird populations have suffered drastically from this creation of mono-cultures We keep hearing the (very valid and commendable) campaigns to save the bees but how do you think bees and other insects will fare if we are trying to feed the world off plants? In the UK our arable farmers attempt to find some balance by leaving areas of fields known as set-aside to encourage bio-diversity but let’s not forget the UK has the highest farming standards in the world and we already know most of our plant-based diet would have to come from overseas where these standards are much lower or non-existent so don’t hold out much hope for bio-diversity there, especially if there is profit to be made. This argument extends to the effect that use of chemical sprays and fertilisers has on water courses. The chemical run-off into water courses has the potential to poison the aquatic eco-systems there, not forgetting that the rivers all run into the oceans. Again, something that is carefully regulated in the UK with the use of buffer zones for sprays and nitrate vulnerable zones for fertilisers but I would not hold out much hope in less regulated countries.
Thirdly, where is all this going to be grown? Are we looking at an even bigger scale of de-forestation than we are seeing already? Anyone who watched David Attenborough’s recent programme cannot have felt comfortable watching the vast swathes of jungle being turned over to palm oil production. This will be exactly the same situation for growing those vegan staples soya, avocado, quinoa etc. Yes I am aware that some animal feed comes from soya but the reality is a large part of what is animal feed is actually by-product and at the end of the day, traditional British systems do not require significant quantities (if any) of this imported feed. We can produce top quality beef and lamb off diets of predominantly grass.
Furthermore, although the specific emissions of CO2 for a gram of plant-based protein might be lower than for feed-lot produced beef, it can never compete with traditionally farmed British meat. The act of cultivating land to allow crops to be planted releases the CO2 stored in the soil. This has to happen every year so it doesn’t matter how small you claim the emissions to be, with no long term sequestration, it does not get to net negative GHG status (unlike our farm).
Don’t get me wrong, we are not sitting around feeling smug. We are constantly looking for ways to improve our farm. As an example, we are gradually converting all our lighting to LEDs. We are also investigating the possibility of clear silage wrap for next season which is much more easily recyclable than the traditional coloured wrap (maybe the subject of a future blog). And looking to the future, I personally am looking forward to the prospect of electric tractors and the opportunities that could bring.
So how have we ended up in a situation where farming is being treated as the enemy? Well I suspect that it stems from the fact that the extreme vegan community (who would do anything they can to stop animal farming of any kind despite the hypocrisy of their arguments) have cottoned on to the fact that the environment is a topic that is getting a lot of attention at the moment and there is a way to exploit that to further their agenda. Couple that with the fact that the farming community has always been very individual and has rarely been capable of speaking with a strong unified voice and the fact that if you put enough propaganda on social media, the general public will be swayed in their view by sheer weight of “evidence”.
However, I really think that BBC “documentary” may have been a bit of a turning point. There was so much anger in the farming community that a supposedly unbiased institution could present something so unrepresentative of, and damaging to the UK farming industry. It feels like that has really kick started a fight-back to get the real facts out there (it galvanised me into writing this, which I’ve been meaning to do for some time now).
As a final point, we should look at this from an aesthetic point of view. The Great British countryside is loved by millions and is one of the most beautiful and diverse places in the world, with fantastic eco-systems. This landscape has been managed by the farming community for hundreds of years with, broadly speaking, the same practices that we have today. Without livestock farming we would lose a huge amount of much loved landscapes to either scrub wilderness or acres of mono-culture.
I have little hope of converting any extreme vegans but what I do hope I can achieve is to re-assure people that you can continue to enjoy your steak dinner or lamb chops without worrying you are destroying the planet. Do your bit by buying locally produced meat from a farm you trust. If you want to, go and speak to your farmer or butcher and ask where the meat came from, how was it raised, what system was used. Most importantly though, enjoy the fantastic quality produce you can get whilst supporting your local economy and environment.
